Replacing chimney flashing after new shingles

Hello, I just had a roofing company replace my shingles on the roof with architecture shingles through the insurance company and they forgot to install the flashing around the chimney as quoted for the entire job. The roof was leaking around the chimney before and after the new shingles. The roofers came out and put a tarp over the chimney and under the shingles to temporarily stop the leak.

The roofers are coming back out to put the new flashing on when it quits raining and as I want the job done right, I'm wondering what the correct "after the fact" procedure is? Do they need to take all the shingles off again and start over on the one side or will they be able to pull back just the shingles around the fireplace to adequately install the new flashing? What other precautions should they be taking (caulking, etc.)?

To do this properly they would have to remove shingles all the way around the chimney.They would then have to remove old flashings.Then install new step tins up the side of chimney,installing along with shingles.Replace backpan.Install new counterflashing on chimney either with a termination bar or re-mortared back into chimney.I always put a nice bead of caulking behind the backpan,while installing on either side.Oh the apron on front of chimney as well.Easier for mr to do then explain.Hope this helps

Maybe they did install new step flashing and flashing and didn't install the new counterflashing. In this case, no shingles would have to be removed and replaced. If they never did install step flashing, get another crew who knows what they are doing. Can you really trust a crew that forgot such an elementary step to do a good job flashing such a vital area?

Thank you for the advice. One other thing is that the chimney box is covered with vinyl siding instead of brick.

I might have to check with my insurance company on getting another crew into finish someone else work. Though that is a good idea. The salesman or contact person failed to tell the workers to add the flashing. All in all, they were in a hurry to get in and out as fast as possible with about 8 workers on the roof scraping old shingles off and stapling new one's down.

What you seem to be describing is a Chimney Chase, not an actual chimney.

The flashings from these are usually already tucked behind the siding.

Bottom has an apron flashing, counter flashed by the siding.

The side(s) have the step flashings, aka, baby tins, also counter flashed with the siding.

The top portion has a pan flashing, also counter flashed with the siding.

Many times either the siding or the sheet metal cap are the causes of leaks on those obstructions. Also, the top hollowed portion of the corner posts have been known to cause the leak issue.

Take photos of the sides and the top of the chimney and post them here for a better clue, if the roof slope is safe to manage for yourself. Don't do it if you are not sure footed on a sloped roof. Have the roofer take the photos for you.

Attached are a couple pictures. They had used caulk around the vinyl and shingles when the roofers came out in a rainstorm thinking it would set. The tarp is nailed in down at the lower edges so it's a bit difficult to get a good photo. I took the drywall off around the fireplace as I plan to re-tile around it and in order to see where the leaking was coming from. The leaking was running down the two outer corners and the right inside corner (looking from outside in).

Can't see much from those pics, the first thing that comes to mind for me is at the two corner post 'outer corners' have no visible signs of step flashing's,
even if there is step flashing's on the side walls 'can't see because of caulking' if they simply ended the flashing's inside the corner pieces than any water running down that area would wind up behind the siding and allow it to get inside.

I would be present when they fix this problem and take note of exactly what they do, and ask for warranty information 'in writing'.

Thanks, Nice to have knowledgeable people available on this site to ensure the job is done right. The work is covered for two years through the insurance company. So, I've taken pictures of the roof install and will be standing over them (w/camera) when the chimney flashing is replaced.

The salesman stated they don't replace most flashings on their jobs and it was his fault that the workers didn't know about it.

Here's what they charged the insurance company. They billed them for a two story, though as a walkout basement, they used the front single level to get on the roof. This quote is for half the roof as the insurance company only paid for the side that had wind damage. So they would only paint half my car I suppose. I paid for the front side + upgrade from 3-tab to a architectural shingle for the entire roof ($2100 + $500 deductible) after reminding the salesman to knock off the two story and chimney work on my particular half of the job. For 16.98 square they made $5396.34.

I know going into this agreement that they were making a bundle and I could have done the work had I the time. Though having it done for me freed up time for other projects. I'm interested in knowing what I would have paid had I got my own estimates and not gone with the insurance company recommended roofers? Going with the insurance company bought me the two year warranty.
